As a top radiologist, Sim Hoffman possesses valuable knowledge on ultrasound imaging devices, including Obstetric scanners that were introduced to the medical field in the late 1950’s. The scanners used in today’s medical science are obviously more advanced, offering real-time images. The method takes advantage of sound, more precisely sounds between specific frequencies, usually 3.5 to 7.0 megahertz, to generate accurate scans.
The System Puts the Puzzle Pieces Together
The system gets valuable information from every reflection and, after mapping them in real time, puts together the picture on the monitor (which is not really a monitor but rather a sonogram). The system is even capable of detecting the fetus’ heartbeat, along with other valuable information, including its size and age. When the examination involves the scanning of the stomach area, it usually requires the patient to arrive with a full bladder.
The Reason for the Full Bladder
When the bladder is full it will show up on the screen black, providing a better contrast and making the fetus and the uterus lighter. Not all OB doctors will ask their patients to arrive with a full bladder, but even those who generally don’t do that will probably appreciate the better picture quality. If it’s the first ultra sound, this fact becomes even more important because of the uterus’ position (still under the pelvis). As a renowned radiologist who frequently attends conferences involving ultrasound technology, Sim Hoffman knows the importance of looking at a high quality picture.
